摘要

黄河黑山峡大柳树坝址区存在大范围的岩体破坏现象。在详细调查区域地质背景条件及区域地震动力作用基础之上，提出了地震动力作用与岩体破坏现象的内在联系，并通过动力模拟试验分析、证明了岩体破坏现象与历史上该地区发生的强烈地震有着密切关系。因此，在目前的工程地质条件下，一旦发生强度较大的地震活动，坝址区所遭受的破坏程度会更大，对拟建的水利工程设施将产生严重威胁。

Abstract

The phenomenon of large-area rockmass failure has been observed in Daliushu dam site on the Yellow River. In order to study the failure mechanism of this rockmass

the intrinsic relationship between dynamic effect of earthquake and rockmass dynamic failure is put forward on the basis of detailed investigations of regional geological environments and regional seismic dynamics; and dynamic simulation experiment are conducted on the failure phenomenon. The experimental results show that the large-area rockmass dynamic failure in Daliushu dam site area is closely related to the meizoseism history. Consequently

the dam site would be damaged more seriously once the seismic activity of the same scale happens.
